Description
Technical Field
The utility model relates to the technical field of medical treatment, concretely relates to portable ultrasonic therapy equipment.
Background
The ultrasonic therapeutics mainly include High-Intensity Focused Ultrasound (HIFU) and Low-Intensity Focused Ultrasound (LIFU) technologies mainly based on High temperature effect. Currently, HIFU is applied to the treatment of clinical tumor and non-tumor diseases, and its action principle is that high-energy ultrasound generates a high thermal effect (instantaneously reaching 70-90 ℃ or higher) in a focal region, so that tissue proteins in a target region undergo thermal coagulation necrosis to generate a physical cell killing effect. It has revealed some safety limitations in clinical applications, such as affected by the movement of the ribs or the peristalsis of the intestine during breathing, the deflection or scattering of the acoustic channel of high-energy ultrasound, the burning of adjacent organs, etc. Reducing the ultrasound intensity is a direct way to improve safety.
The ultrasound intensity is reduced, but to ensure a local and sufficient therapeutic effect, synergy of Microbubbles (MB) is required (fig. 1). In the LIFU + MB treatment system, MB refers to a class of lipid, protein or high molecular polymer coated gas core particles, such as micron vesicles which are widely applied to a clinical ultrasonic contrast agent SonoVue and are matched with ultrasonic energy in a laboratory development stage, the diameter of the micron vesicles is 1-10um, the micron vesicles can stably exist in blood circulation, when the micron vesicles are irradiated by low-energy ultrasonic waves, the gas cores of the microbubbles generate resonance movement, local energy is amplified, and a treatment effect is generated. Although the treatment mechanism is not completely clear at present, in vivo and in vitro experiments show that the low-intensity ultrasound combined microbubble has a tumor treatment effect similar to that of high-intensity ultrasound, and the use of MB reduces the intensity threshold of cell death caused by pure ultrasound and improves the treatment safety. Therefore, the effectiveness and safety of LIFU + MB are worthy of affirmation, and the method is a new treatment technology with good clinical transformation application prospect, and brings treatment hope for different disease patients, especially for tumor patients with refractory diseases and traditional chemotherapy drug resistance. Therefore, the development of a low-intensity focused ultrasound probe with stable performance and convenient operation is an important part of the treatment system.
